basic php5 oop question

How do I call the methods of another object from inside another object?

This doesn't seem right:

      3 class errObj{
      4
      5   public function displayErr($msg){
      6
      7     echo $msg;
      8     exit;
      9
     10   }
     11
     12 }
     13
     14 class doSomething{
     15
     16   public function doingIt(){
     17
     18     $msg="An error happened";
     19     $err_obj=new errObj();
     20     $err_obj->displayErr($msg);
     21
     22   }
     23
     24 }
     25
     26 $obj=new doSomething();
     27 $obj->doingIt();

Thanks in advance for any insight.

That syntax is alright. Is it throwing an error when you try that?

No error, just seems bad.

If everytime I want to use the errObj inside another object, I have to create it inside that other object, seems tedious.

in your case, you may want to use a static function. Here would be the rewritten code:

class errObj{
	public static function displayErr($msg){
		echo $msg;
		exit;
	}
}
class doSomething{
	public function doingIt(){
		$msg="An error happened";
		errObj::displayErr($msg);
	}
}

$obj=new doSomething();
$obj->doingIt();
